Yes they are with SPR. The dyno sheet was with the cams, they are locked out though. Ideally would have been better with lighter valve springs and limiters instead of lockouts... You live and learn.

Sounds very healthy!

I used 127550 cams in my SC build. Just so you know, I started out with FRPP Limiters but had some valvetrain/phaser noise at start up. Under investigation the little limiter spring in the passenger phaser was broken. While I am sure this did not cause the noise when I put the motor back together I used Livernois Lockouts and no more noise. Go figure!

Yeah thats also part of the reason why I did lockouts, didn't want to have issues with the limiters.
